Plot summary
A man named Stewart Gimbley ( Joshua Malina ) believes he is a werewolf, so he offers Shawn and Gus three times their normal rate to tie him up and observe him. Unfortunately, they fall asleep and wake up to find Stewart missing, their window broken, and a tuft of animal hair. Their investigation leads them to a psychiatrist ( David Naughton ) and a Wiccan ( Larisa Oleynik ), each with possible secrets. This is also the episode where Henry has to keep touching a truck to win it.
